Dozens of protestors gathered outside the European Commission’s office in London on Saturday to condemn the EU’s policies towards non-European migrants, which are blamed for the deaths of hundreds of people in a shipwreck in the Mediterranean last week.

The demonstrators chanted, “Don’t let them drown” and carried banners, reading, “Syrian refugees welcome here,” “Blood on your hands,” as well as other placards.

They called on the EU to restart the Mare Nostrum search and rescue operations in the Mediterranean Sea, which helped 150,000 migrants safely arrive in Europe in 2013.
